512MB DDR 400 ECC module

This 512MB DDR 400 (PC 3200) module provides ECC error correction in an unbuffered design. It suits administrators maintaining legacy servers or workstations that require 184-pin DDR SDRAM. The CL3 3-3-3 timing and 2.60V operation match original platform specifications.

Fits 184-pin DDR slots directly

The stick installs in standard 184-pin DDR sockets without registration buffers. ECC capability protects data integrity in always-on environments. Unbuffered layout keeps latency low for the chipsets that expect it. No heat spreader is fitted, leaving clearance for tight DIMM spacing.

Sustained load stability from ECC

Error-correcting code detects and corrects single-bit errors during continuous operation. CL3 timing remains consistent at the rated 2.60V supply. Absence of a spreader means airflow across the PCB manages thermals. The module delivers the reliability profile expected of ValueRAM server memory.

Questions about this item

What 184-pin DDR speed does this module run at?

It operates at DDR 400, also labelled PC 3200, with a CAS latency of CL3 and 3-3-3 timing.

Does the 2.60 V unbuffered ECC design run hot or loud under constant load?

The module has no heat spreader and no moving parts, so it adds no fan noise; heat output is typical for standard 2.60 V DDR memory.

Which server boards accept 512 MB 184-pin unbuffered ECC DDR sticks?

Any system that supports 184-pin DDR 400 unbuffered ECC memory can use this 512 MB module.
